Injection molding machine factory tutors you how to do a good job of safety management before and after the operation of injection molding machine

    The safety management before and after the operation of the injection molding machine can make the injection molding machine have fewer defects, complete functions, reduce the number of failures, improve the operation efficiency and prolong the service life of the injection molding machine. Therefore, the injection molding machine factory teaches you how to do a good job in safety management before and after the operation of the injection molding machine.

    Before operation:

    1. Before the operation of the injection molding machine, check whether there is water and oil in the electrical control box. If the electrical appliance is damp, do not start it. Maintenance personnel shall blow dry the electrical parts before starting the machine.

    2. Before the operation of the injection molding machine, check whether the power supply voltage is consistent. Generally, it shall not exceed ± 6%. Add enough plastic into the hopper. According to the requirements of different plastics, some raw materials are dried first. Cover the heat insulation cover on the cylinder, which can save electric energy and prolong the service life of electric heating ring and current contactor.

    3. Check whether the emergency stop switch and the front and rear safety door switches of the injection molding machine are normal. Verify whether the rotation direction of motor and oil pump is different. Check whether all cooling pipes are unblocked for a long distance, and supply cooling water to the oil cooler and the cooling water jacket at the end of the barrel. Before the operation of the injection molding machine, check whether there is smooth oil in each moving part and add enough smooth oil. Turn on the electric heating and stop heating each section of the barrel of the injection molding machine. When the temperature of each section reaches the request, it shall be kept warm for a period of time to stabilize the machine temperature. The holding time varies according to the requirements of different equipment and plastic raw materials.

    4. Don't cancel the function of the safety gate for convenience. Pay attention to the temperature of the pressure oil. The oil temperature should not exceed the regular range. The ideal working temperature of hydraulic oil should be 45-50 ℃, which is generally in the range of 35-60 ℃. Pay attention to adjusting the travel switches to prevent the injection molding machine from hitting during operation.

    After operation:

    After the operation of the injection molding machine is completed, the plastic in the barrel shall be cleaned to prevent residual material oxidation or long-term heating synthesis. The mold shall be opened to keep the toggle mechanism locked for a long time. The workshop of Shanxi injection molding machine consumer manufacturer must be equipped with lifting equipment. Be very careful when assembling and disassembling the mold to ensure safe consumption.
